Tlhahiso ea Seamless Tube e Chesang - Sehlopha sa Royal 

Ho roala ho chesang (extrudedphala ea tšepe e se nang moroalo): pota-potileng tube billet→ho futhumatsa→ho phunya→bidika-tharo sefapanong, ho bidika ho tswelang pele kapa extrusion→ho hlobola→boholo (kapa ho fokotsa)→phodiso→ho otlolla→tlhahlobo ea hydraulic (kapa ho lemoha phoso)→ho tshwaya→polokelo

Thepa e tala bakeng sa phala e se nang seamless ke "round tube billet", 'me embryo e chitja e lokela ho khaoloa ka mochini oa seha ho holisa li-billet tse bolelele ba mithara e le 1, ebe e isoa seboping ka lebanta la conveyor.Billet e kenngoa ka seboping ho futhumatsa, mocheso o ka bang likhato tse 1200 tsa Celsius.Mafura ke hydrogen kapa acetylene.Taolo ea mocheso ka sebōping ke taba ea bohlokoa.Ka mor'a hore tube e pota-potileng e tsoe ka sebōping, e tlameha ho phunngoa ka ho phunyeletsa khatello.

Ka kakaretso, motho ea phunyang lebili la khoune ke ea tloaelehileng haholo.Mofuta ona oa ho phunya o na le ts'ebetso e phahameng ea tlhahiso, boleng bo botle ba sehlahisoa, katoloso e kholo ea bophara ba perforation, 'me e ka apara mefuta e fapaneng ea tšepe.Ka mor'a ho phunya, "tube" e pota-potileng e kenngoa ka ho latellana ho pota-potiloe ka litsela tse tharo tsa ho pota-pota, ho phunya ho tsoelang pele kapa extrusion.Ka mor'a extrusion, tube e lokela ho tlosoa bakeng sa boholo.Ho cheka mekoti ka lebelo le phahameng la rotary cone ka har'a billet ho etsa tube.Bophahamo bo ka hare ba phala ea tšepe bo khetholloa ke bolelele ba bophara ba ka ntle ba mochine oa ho phunya oa mochine oa boholo.Ka mor'a hore phala ea tšepe e be boholo, e kena ka tora e pholileng 'me e pholile ka ho fafatsa metsi.Ka mor'a hore phala ea tšepe e pholile, e tla otlolloa.

Ka mor'a ho otloloha, phala ea tšepe e romeloa mochineng oa tšepe oa tšepe (kapa tlhahlobo ea hydraulic) ka lebanta la conveyor bakeng sa ho lemoha liphoso tsa ka hare.Haeba ho na le mapetsong, li-bubble le mathata a mang ka har'a pipe ea tšepe, li tla fumanoa.Kamora tlhahlobo ea boleng ba liphaephe tsa tšepe, ho hlokahala khetho e tiileng ea matsoho.Ka mor'a tlhahlobo ea boleng ba pipe ea tšepe, penta nomoro ea serial, tlhaloso, palo ea lihlahisoa tsa tlhahiso, joalo-joalo ka pente.'Me a phahamisoa ka tlung ea polokelo ka crane..
